Ah summer: the time for cookouts and fireworks and long days at the beach trying not to check your email. It's also a time to finally use all those airline miles and hotel points you've accumulated to get a free place to stay and free transportation to get there.

A few weeks ago, I got two fat envelopes in the mail. Each one held a new credit card inside along with instructions on how to use that card. Then, when I stopped at my local grocery store, at Nordstrom, even the corner liquor store, each had a new reader with a slot at the bottom into which I could slide those new cards.

As details filter out about the Home Depot hack (and many, many more data breaches), you can't help but ask: How did this happen -- especially when the company was supposed to adhere to specific safety regulations or else lose its capability to process credit card transactions?

Small and medium-sized businesses may think they're immune to the kinds of attacks that wreaked havoc on Target last year, but they're susceptible to the same nefarious forces -- sometimes even more so, as they can lead hackers to a bigger prize.

Cyber resilience will be particularly important as Australian organisations face increased pressure to quickly detect, respond to, and manage the repercussions of breaches in the wake of 2018’s Notifiable Data Breaches (NDB) scheme.
